Been following this thread for awhile. While I have no background in aircraft, I find them fascinating and wanted to share a link which has helped
detail some of the frames/programs mentioned. List of experimental aircraft
I am long time follower but first time poster in this forum. I wasn't sure where to put this but here it is. I live in the southwest of the country.
My wife took these photos at work last Wednesday around 12:30 p.m. She said whatever made this contrail was moving very fast from west to east and
went from horizon to horizon in a matter of minutes. It was a windy day and I thought it was strange the contrail didn't dissipate. She said there
were others planes in the sky making contrails, but those all dissipated rapidly. I thought it looked very odd compared to others I've seen. It also
appears to be above the other contrails. Thoughts?
Those are very common contrail formations. When the atmospheric conditions are right, I see airliners produce identical contrails on a daily basis.
Unfortunately, some years ago, somebody took a picture of one and described it as "doughnuts on a rope" and narratively connected it to a mythical
secret aircraft. Now, lots of people freak out when they see contrails like this.
It was my understanding that the second test article had a different lay up on the wings to alter the behavior of the aeroelastic divergence. This is
from memory from years ago so I would welcome any clarification.
In your photo, you've got other persistent contrails, so the observation that all the others dissipated rapidly is not right. Also, if you look at the
types of clouds in the photo, you've got cirrus and cirro-cumulus, which is a magic condition for persistent contrail formation. Those cloud types
tell you that you've got saturated upper atmo air that's very unstable.
Long time lurker here, but just read this whole thread and a few others pertaining to a certain topic. Its taken me a whole week to get through it all
and I just wanted to thank everyone for such great info/discussion
